What percent of the questions did Justine answer incorrectly?

Respuesta :

For A the answer is 85% correct. Then 15% incorrect. I got the number correct by taking 68 and dividing by 80. To get the number incorrect I took the 15 other questions (80-68) and did 12 divided by 80 to get the 15% incorrect.
